The technical field to which the invention relates

The invention relates to the automatic integration of devices such as a lamp, in such a network system, the network lighting system, so that the user does not have to set up or configure a new device or a lamp, respectively.

The prior art inventions

Currently, in most environments, lighting incorporates separate lighting units that have a simple, unambiguous connection with dimmer switches. These environments do not allow convenient and centralized management, for example, remote control units, and a light providing illumination environment. However, in the foreseeable future, this will change due to the fact that the network lighting systems will become more widespread, which will make possible the best solutions for energy efficiency, providing lighting environment, wireless remote control and so on. Despite the fact that the lighting systems are more energy efficient than separate blocks of lighting, they are also more complex, for example, in relation to the setup and configuration of the lamps. An example of a complex lighting unit for use in the home is the LivingColors lamp™ the applicant.The LivingColors lamp™ contains remote control, which allows the user to conveniently adjust the color and intensity of light, in particular to select your preferred color from the color range. The user can also manage multiple LivingColors™, shaping the lighting system in the home, as well as to control multiple lights with one remote control.

Patent WO 2008/068693 A1 relates to the replacement of devices in the network, similar to the lighting control system, in particular wireless network. For hot swap of the device operating data device to determine the actual functionality that is stored in the storage device. After physically replacing the device stored data is downloaded to a new device. Thus, it is possible quick and simple replacement of an existing device on the network.

The invention

The aim of the invention is the provision of a method and controller, which allow for the easy integration of new devices in the network system, in particular, without the need of any user interaction with the system or simply need a minimum of user interaction with the system, such as connecting a new device to the network and turn it on.

The objective is achieved by the independent claims. The AOC is e, options for implementation are represented by the dependent claims.

The basic idea of the invention is to provide a kind of automatic process of commissioning of such new devices as lamps that are integrated into the lighting system. In particular, the invention provides an automatic backup functionality lamp lighting system on the new lamp, which is integrated into the lighting system. The new device, unlike patent WO 2008/068693 A1 is not a replacement for another device and is added to the network system as an additional device. Therefore, not only the duplicated data is copied to a new device, but is determined by the reference device, which, for example, largely coincides with the new bulb mode through the availability of capacity, similar to the capabilities of the new device and its functionality are copied to the new device to the new device worked immediately without the need of any user interaction with the system. In particular, the invention is applicable in a networked lighting systems in order to make easier the operation of the lamps of the lighting system, and the integration of new lamps in the lighting system is much more Udo is poor.

A variant embodiment of the invention provides a method of automatic integration of devices in a network system containing automatically performed steps:

discovery of the new device, which will be integrated in a network system,

- determining a reference device of the network system, and

- copy functionality reference device to your new device.

Functionality can, for example, contain a particular state of the reference device, which is determined, for example, through such settings as the settings of the color and intensity of the lamp as that of the reference device so that the user no need to configure a new lamp or device. In addition, the functionality may contain certain modes of operation of the reference lamp, defined, for example, by means of lighting effects that can be created using a reference lamp or device. Thus, the new device can be fully integrated into the network without the need for manual adjustment by the user, and immediately after integration can work as already integrated device.

In an additional embodiment of the invention

the detection step of the new device is TBA, which will be integrated in a network system, in addition, may contain a determination of the capabilities of the new device, and

the step of determining a reference device of the network system may include determining a reference device of the networked system with capabilities similar to the capabilities of the new device. For example, if in a networked lighting system should integrate the new lamp, the method can automatically detect that a new lamp is able to provide lighting within a certain range of colors. Then the method can determine the lamp networked lighting system, for example an existing working lamp or old lamp networked lighting system, which can generate light within a range of colors, which is either identical to the range of colors of light that can be created with a new lamp, or contains a range of colors of light new bulb. Determining a reference device of the networked system with capabilities similar to the capabilities of the new device is a kind of coincidence opportunities and may not only contain, in the case of lamps as network devices of the lighting system, the range of colors created lighting, but some features such light, such as intensity and such created lighting effects, dynamic lighting effects.

In addition, a variant embodiment of the invention stipulates that

the step of determining a reference device of the networked system may contain a determination device network system, which was disconnected from the network system, and, in addition, may contain identifying opportunities disconnected devices. This makes possible a rapid and simple replacement of the device network system, without the need for regulation of the replacement device to work the same as the replaced device. In addition, broken device can easily and quickly be replaced in this embodiment, the inventive method.

In an additional embodiment of the invention the step of defining device network system, which was disconnected from the network system may include restoration opportunities disconnected the device from the storage device on the subject of opportunities disconnected devices. For example, the network system may register any device in the storage device together with its capabilities. In addition, the network system may register in the storage device, if the device is removed from the network system, in particular disconnected or broken. The term "isolated" means the device is removed from the system in the same way, to the to and removing devices from the network devices. Stored data on disconnected devices can later be used to add new devices to the system and simplify replacement of disconnected devices new devices. Procedure detach devices can also be saved. Thus, if detached many devices, and then later add a new device it is stored or other specific procedure can be used to identify matching or similar device. For example, first add the device may be opposed to the oldest from remote or disconnected from the stored devices. Or first add the device may be opposed to the last remote devices. Can be used a variety of strategies to match new device disconnected device to best meet user requirements and more sensitive mode of operation of the method in accordance with the invention with the simultaneous replacement of multiple devices.

Another variant implementation of the invention stipulates that the search capabilities disconnected devices from the storage device on the subject of opportunities disconnected devices may include determining a reference device of the networked system with capabilities similar to the capabilities of the new device is as disconnected from the stored devices. This can be achieved, for example, by searching for the device among the stored disconnected devices, which can be, for example, similar to the new devices possible, instead of, for example, to boot the first dataset is disconnected the device from the storage device and to use the opportunities of this dataset for the new device, which can lead to the fact that the new device does not use all its functionality.

Detailed description of embodiments

In subsequent functionally similar or identical elements can have the same reference numbers. Now the invention is explained through networked lighting system, as an example of the network system. Lamps or lighting units of this network lighting systems are devices. However, the invention is not limited to use in a networked lighting systems, and can be applied in any network system, such as a network management system house or office or similar. Moreover, in the following description, the terms "light" and "light Assembly" used in esults as synonyms, describing one and the same technical means. If in the following description uses the term "lighting system", we mean the network lighting system as an option for implementation of network systems, as applied to the present invention.

Modern lighting systems allow you to adjust and configure various settings of the lamps, such as color and intensity of lighting and lighting effects. However, the configuration and setup of a new lamp, which is integrated into the lighting system can be time-consuming and tedious due to the usually large number of parameters that can be adjusted by the user.

Now, the present invention allows the user to quickly integrate the new lamp into the lighting system, without the need for any regulation. The process of integrating a new lamp, performed in accordance with the invention, explained in the following with reference to Fig.1, depicting the sequence of operations implemented in software tools inventive method for integrating the lamp.

In the first step S10, by the lighting system finds a new lamp. For example, if the new lamp LivingColors™ should be integrated into the lighting system, consisting of multiple LivingColors lamps™, a new lamp is automatically assigned to N. the first identifier, see step S101 to the step S10 shown in Fig.2, which depicts the step S10. The appointment of a new identifier can be performed using a wireless remote control lighting system, if it receives a wireless signal from a new lamp, which may contain a unique network address of the new lamp, such as some sort of MAC address (access control environment data). However, it should be noted that in many cases, addresses are assigned to devices and installed at the factory. Thus, this step is required only if the lamp has no address. On subsequent podate S102 to the step S10 (Fig.2) wireless remote control device may query the capabilities of the new lighting bulb such as an adjustable range of colors, lighting, lighting effects, etc.

In the second stage S12/S13 is determined by reference lamp lighting system. The determination of the standard lamp contributes to the determination of the location of the lamp lighting system with lighting, similar to the lighting features of the new lamp. In accordance with the invention provided and outlined in Fig.3 and 4 two different ways of setting the reference lamp.

The first method, as shown in Fig.3 and defined by the step S12, the content is t, the following sub-steps: podate S121 lighting a new lamp in accordance with the request at step S102 is compared with the possibilities of lighting lamps, already integrated into the lighting system. This comparison process is not a simple comparison of two values, and is a more complex process of finding the lamp lighting features that are most similar to the lighting features of the new lamp. The comparison process can be influenced by various aspects: one aspect is the current settings of the lighting lamp system and the available settings of the lighting of the new lamp. Another aspect is the lighting effects generated by the lamp system and the ability to create lighting effects through a new lamp. An additional aspect may be, for example, the power consumption of the lamps of the lighting system. In subsequent podate S122 one lamp lighting system with similar features lighting is defined as the reference lamp for a new lamp on the basis of the result of the comparison process of step S121. In a nutshell, the new lamp is configured so that it operates as existing lamp lighting system that best matches the capabilities of the new lighting the lamp, for example, which has the greatest similarity of its features lighting with new lamps. For example, if a new lamp is able to provide orange light and one lamp lighting system configured to generate the light ìנאםזוג}, the last lamp is defined as the reference lamp for a new lamp, and its settings to create a orange light is copied to the new lamp so trim, so she created an orange light immediately after integration. Thus, the user sees a reasonable work by default for a new lamp, integrated into the lighting system.

The second method of determining the reference lamp is shown in Fig.4 and indicated by the step S13: the first podate S131 is determined by the lamp, which was disconnected from the lighting system. Disconnected the lamp may, for example, be a remote bulb or a broken lamp. After disconnecting the lamp lighting, including its settings and configuration settings are stored in the storage device to the disconnected lamps together with its identifier in the lighting system. Lighting can also be saved before removing the lamp, for example, at any time during the life of the lamp, in the storage device to the disconnected lamps, and if the lamp is disconnected, it can be set stamp in the storage device so that it's clear what light actually is disconnected. Then explained the process of determining the reference lamp in accordance with the second method. For example, if the lamp, represent the work by green light, and with ID 3 in the lighting system, disconnected, for example, through its separation from the lighting system or by switching it off, the options for customizing the appearance of the green light and ID 3 are stored in the storage device to the disconnected lamps. On podate S131 may be used for several identification strategies lamp. For example, it may be determined lamp, which was disconnected last. In addition, among the disconnected lamps can be found the lamp, which has the best possible light, similar to the lighting features of the new lamp, all disconnected bulbs stored in the storage device. The following podate S132 identifies opportunities for lighting certain disconnected lamp. For example, if podate 131 was determined disconnected lamp with ID 3, its settings, representing the green light, can be loaded from the storage device to the disconnected lamps. Alternatively, it may be determined lighting disconnected lamps, which are best suited for a new lamp.

Returning now to Fig.1, the process continues to step S14: at this stage, the functionality of a specific reference lamps are copied to the new lamp for the full integration of the new lamp into the lighting system. Functional POS of the property can be transferred to the new lamp through a wireless communication, for example, controlled through wireless remote control lighting system.

Fig.5 shows the integration of the new lamps in the lighting system in such a wireless remote control as a remote control lamp LivingColors™: a new integrable lamp is indicated by reference number 14. Reference number 10 denotes an existing lamp lighting system. Reference number 12 indicates the lamp is disconnected from the lighting system. The lighting of this lamp 12 were saved in the device 16 data storage for detached lamps after disconnecting the lamp 12. Now, in accordance with the invention is the process of integration in the following way. If you include a new lamp 14, it is detected wirelessly by the wireless remote controller 18 remote control lighting system (step S10). Then the remote control 18 remote control automatically initiates the process of integration without any user interaction with the system. It is performed by determining the lamp 10 as the reference lamp (step S12) and through direct copying capabilities illumination lamp 10 on the new lamp unit 14 (step S14). Alternatively, the device 18 remote control can determine disconnected La the PU 12 of the device 16 for storing data in the reference lamp (step S13) and the possibility of covering this disconnected lamp 12 can be copied from the device 16, data storage on the new lamp unit 14 (step S14).

As described above, the invention, in particular, allows us to solve two problems of complex lighting systems:

1. If the user adds a new lamp in a lighting system, the lighting system automatically knows how to use it.

2. If the user replaces (broken or disconnected) lamp with a new lamp, it works the same way, as I used an old lamp. For example, if the old lamp was orange light under the table in a certain environment, the user wanted a new lamp was performing the same task. In particular, it is difficult in systems where connectivity is wireless, because there is no (simple) way to know where to put the new lamp: the system does not know that the new lamp is placed under the table.

As explained above, the invention offers a solution to both problems, without having to perform any additional steps, in addition to installation, connectivity new lighting to the lighting system, which, as a rule, goes automatically turns on the light Assembly.

In accordance with the invention, problem 1 can be solved so that after integration of the new lamp in a lighting system, it had a view in the system in PR is dmet, whether the light Assembly with the same technical characteristics. For example, in a lighting system consisting of multiple LivingColors lamps™, the system can be attached new LivingColors lamp™. The LivingColors lamp™ will get some address or identifier by the lighting system, such as ID 1. It will have some functionality, such as displaying an orange light in a certain environment. Now, a new LivingColors lamp™ is added to the system. It through the system is given a new ID, say ID 2. The system sees that the unit 2 lighting has capabilities similar to unit 1 lighting, and, therefore, will copy the functionality of the unit 1 lighting (i.e. the submission of orange light on the unit 2 lighting. Of course, when using another type of a new lamp (for example, a lamp that can provide cool and warm white light), then the system will attempt to correlate it with existing lighting unit with such features, for example, conducting a search for an existing lighting unit with similar features lighting. Thus, the new lamp is used in exactly the same way as was used and the old bulb with the same technical characteristics. Thus, the user sees the reasonable operation of the new source is the infrared light by default.

For problem 2, the system can memorize the functionality performed, for example, through the last off of the lighting unit. The first new connected lamp can be controlled in exactly the same way as last turned off the lamp. For example, the system can be connected lamp LivingColors™. The LivingColors lamp™ gives some address or identifier by the lighting system. Let it be ID 1. If it is disconnected, the system remembers the last connected the power light was lighting unit with ID 1. It will also remember the functionality that was available in the unit 1 lighting. Now connect the new light Assembly. He will get the ID, for example 2. Now, the system will try to use 2 same as 1. This means that it will search functionality 1 (i.e. the submission of orange light) and apply them to 2. Thus, provided that the user replaces only one lamp at a time, there is no additional phase commissioning required for the replacement of lighting units. The process can be modified to give the user the ability to replace many light sources at the same time. This system can memorize the order in which the lamp ataegina the tsya, and to add their functionality to the queue q. Whenever the lamp is disconnected, q will be removed from the queue. A new lamp will be the same with this functionality. Thus, the user can replace many lamps at the same time, provided that he attaches a new lamp in the same order in which disconnected the old lamp. (Some users may find it more appropriate to perform this process in reverse order, and in this case can be used a stack-based storage device). In addition, the system can memorize the technical characteristics of each switchable unit lighting. For example, she can remember that the LivingColors lamp™ (representing orange color under the table) is disconnected with ID 1, and the light that is able to provide cool and warm white light disconnected with ID 2. Whenever you connect the new lamp that can provide cool and warm white light, the system will compare their technical specifications technical specifications lamp, which was usually the ID 2. Whenever you connect the new lamp, capable of representing color, the system will compare their technical specifications lamp, which was usually the ID of 1.

The invention can be applied to l the battle system lighting with multiple light sources, for example, if the practical application in lighting homes, shops and offices. In particular, it is suitable for simple configuration of light sources and commissioning of lighting, in particular, by end-users in the home environment.

At least some of the functionality of the invention can be performed by hardware or software. In the case of the variant implemented in software tools can be used once or many standard microprocessors or microcontrollers to process one or many of the algorithms that implement the invention.
